IDM rider Nekvasil back on top in the BMW Motorrad Race Trophy – Kiyonari claims next win in the BSB.
Riders in the SUPERBIKE*IDM scored well at the weekend – The BMW Motorrad Race Trophy now consists of 57 competitors from 19 countries.
Munich, 23rd July 2014. It remains exciting at the top of the BMW Motorrad Race Trophy standings: the lead has now changed hands six times. IDM rider Marco Nekvasil (AT) regained the lead with a successful weekend in Schleiz (DE). However, his rivals will have another opportunity to score Race Trophy points this weekend. Meanwhile, Ryuichi Kiyonari (JP) won again in the British Superbike Championship.
BMW Motorrad Race Trophy: Nekvasil storms back to the top.
The worldwide racing community of privateer BMW Motorrad riders continues to grow. And out of them, 57 participants from 19 countries on five continents and 15 different championships have now registered for the BMW Motorrad Race Trophy.
This week saw another change at the top of the standings: Austrian Marco Nekvasil, who races in the SUPERBIKE*IDM series, regained the lead with 162.50 Race Trophy points. He is followed in second and third by Cyril Brunet-Lugardon (FR) and Emilien Jaillet (FR), who compete in the French Superbike Championship and both have 143.00 points to their names. As Brunet-Lugardon has claimed one win more than Jaillet this season, he is in second place. Race wins and positions are the deciders if two or more riders have the same number of points.
Nekvasil and his fellow BMW riders in the International German Motorcycle Championship (SUPERBIKE*IDM) were once again successful at the fifth round of the season in Schleiz (DE) last weekend, scoring more valuable Race Trophy points. In the Superstock class, Nekvasil won his sixth race of the season on the BMW S 1000 RR fielded by Interwetten Racing by Fritze Tuning. He won the second of two races at Schleizer Dreieck, having previously finished runner-up in race one. The first race was won by another BMW Motorrad privateer, Dominik Vincon (DE/BMW Stilgenbauer). This was Vincon’s first win of the season. Third place in race two ensured he was back on the Superstock podium. Leon Bovee (NL/Van Zon Remeha BMW) finished fourth and fifth. Lucy Glöckner (DE/Wilbers BMW Racing) showed plenty of fighting spirit: she was taken to hospital for a check-up after crashing out in Saturday’s first race, but this did not prevent her from finishing fourth in race two on Sunday.
In the premier class, the Superbike category, Markus Reiterberger (DE/Van Zon Remeha BMW) claimed another two podium finishes. He was third behind Max Neukirchner (DE) and Xavi Fores (ES) in both races. Reiterberger thus climbed into fourth place overall in the Race Trophy standings. Stefan Nebel (DE/Wilbers BMW Racing) came home sixth and eighth on his BMW HP4, while Bastien Mackels (BE/Van Zon Remeha BMW) was ninth and fifth.
The Race Trophy standings could once again take on a completely new look this weekend, as four race events present participants with opportunities to score heavily. Misano (IT) hosts the Italian Motorcycle Championship (CIV), the “8 Hours of Suzuka” (JP) takes place in the FIM Endurance World Championship (EWC), the Canadian Superbike Championship (CSBK) will be held in Mopar (CA), and the Brazilian Superbike Championship (BRSBK) heads to Brasilia (BR).
British Superbike Championship at Brands Hatch.
BMW Motorrad Motorsport once again had cause to celebrate in the fiercely-competitive British Superbike Championship (BSB) last weekend. The Grand Prix Circuit at Brands Hatch (GB) hosted the fifth round of the 2014 season. Ryuichi Kiyonari (JP), who claimed a historic maiden win for BMW in the previous round of the renowned BSB at Knockhill (GB), was once again victorious. Buildbase BMW Motorrad rider Kiyonari continued his run of dazzling form on the BMW S 1000 RR at Brands Hatch, winning the first of two races. In a dramatic second race, which had to be restarted twice due to a crash and a downpour, Kiyonari was again involved in the battle for the lead, before retiring late in the race. Swiss rider Patric Muff (Bathams Prize Winning Ales) crossed the line in 15th place in race one to finish in the points. Kiyonari’s team-mate Lee Jackson (GB), one of the top riders in the Superstock class, also raced in the Superbike races at Brands Hatch, coming home 16th and 18th.
In the Superstock race, Jackson finished third to make another appearance on the podium. He was followed over the line just four tenths of a second later by fellow BMW rider Hudson Kennaugh (GB/Linkxel Trik Moto Racing) in fourth place.
FIM World Superbike Championship at Laguna Seca.
The weekend before last featured one of the highlights of the World Superbike Championship (WSBK) calendar. The experts from BMW Motorrad Motorsport travelled to California, where the famous Laguna Seca Raceway (US) hosted the ninth round of the season. The circuit, with its iconic Corkscrew, may have been new territory for Sylvain Barrier (FR) of the BMW Motorrad Italia SBK Team, but the man on the BMW S 1000 RR soon found a good rhythm. He finished third in the EVO class and 12th overall in the opening race. However, the Frenchman, who missed three months earlier this year after a serious car crash, suffered a set-back in race two. He crashed out after being touched by another rider. The result was a fractured left heel. Last week, Barrier successfully underwent surgery and he is confident he will be back in action at the next round, which takes place in Jerez (ES) at the start of September.
Gabor Rizmayer (HU) continued to fill in for the injured Imre Toth (HU) for BMW Team Toth. Rizmayer finished 17th and 15th on the Superbike version of the RR. Team-mate Peter Sebestyen (HU), who raced in the EVO class, failed to finish the first race and did not start the second.

Moham Brings Home 7 Wins and 6 New Class Track Records!!
This past weekend proved to be successful, yet again, for MRA racer Shannon Moham. Racing in Fountain, CO at Pikes Peak International Speedway, brought Hot temperatures and Intense racing! The weekend started out phenomenal for Moham with Saturday proving to be his day on the R6 and SV650. Moham brought home 3 Race Wins in Lightweight GP, Lightweight Endurance and Heavyweight Endurance!! He also set three Class Track Records in all of those races!!! Moham, also known as “Marathon Man”, continued on his “B” bike (R6) in Middleweight Super sport and Heavyweight Super sport, bringing home 2nd place in both classes for races he doesn’t usually participate in. Not bad for a Saturday…..
As Team Moham continued into Sunday, the temperatures continued to soar. But that didn’t stop Moham from continuing to dominate on the track. Moham started out his day with an incredible win in Middleweight Superbike on his “A” bike, Yamaha R6. He didn’t stop there! With a back-to-back race on his SV650 in Modern Vintage GTU, Moham Again brought home the Race Win. Lunchtime provided a small reprieve but the afternoon held a full schedule for the Moham race team.
Moham, once again, dominated the grid during the MRA’s Premier Race of the Rockies, and delivered that first place win! The win included Moham setting another Class Track Record for the Race of the Rockies GTU at PPIR! During Moham’s interview on the podium he stated, “First of all, I have to thank my wife, who is running up here from the pits, for being a complete rock star. And I want to thank my daughters Denver (5) and Dakota (2). Especially Denver, for getting out on pit wall and signaling me with her florescent orange gloves during my races!”
The afternoon continued to be, yet again, eventful for Moham, as he brought home another Race Win in Super twins GTU as well as his 6th Class Track Record for the weekend!
The epic race battle of the weekend, however, was in Heavyweight SuperBike. Moham’s last race of the day. #945 and #599,Pete Tabor, battled it out the entire race. It was quite the race to watch. Moham led, then Tabor, then Moham, then Tabor….You get the gist. Moham states, “I had Pete set up for the last lap before we entered turn four I was going to take him, but as I exited turn three the rear end of the bike let loose. I guess I got voted for the “best save” of the weekend. I thought I was going head over heels over the bike. But, I managed to save it and ended up coming in second behind Tabor! Great Job on Pete for hangin in and totally battling with me the entire race. It was definitely an awesome and challenging race and I can’t wait to do it again next round”!
Moham brought home 7 Race Wins and set 6 New Class Track Records. Not a bad weekend at all. He would like to thank the following sponsors for their amazing support: : Nordic Nursing, Dunlop Tires, Race Tech, Evergreen Recreational Vehicles, La Mesa RV, Woodcraft, Armour Bodies, Vortex, Silkolene, FMF, Galfer, K&N Filters, Renegade Fuel, GPR Stabilizers, Lockhart Phillips, Pit Bull, Bazaaz Performance, Motonation, Rocky Mountain Photo, World Wide Bearings, Ogio, Rex at Tri City Cycle, Vickery Motorsports, Team Papajohns, and, last but not least, Mom.

Morgan Hill, CA – Meen Motorsports endured through difficult conditions at Mid Ohio Sports car course. Yet Jake Lewis, coming fresh off of his first ever Daytona Sportbike victory at Mazda Raceway Laguna Seca, carried some momentum into the second to last round of the AMA Championship, capturing another first place podium finish.
Due to the rain, making dangerous track conditions, the AMA paddock was limited to only a few laps on Saturday, leaving the Meen Motorsports riders with little or no seat time. Rescheduling the weekend, each class was then programed for a two race sequence on Sunday. For race one the riders took to the track for a forty minute warm up followed by a grid and go style, shortened 14 lap race. All riders gridded by their points standing.
Running second in the Daytona Sportbike championship, Lewis was gridded on the front row for race one, alongside Danny Eslick and Jake Gange. Lewis rode his Yamaha YZF R6 first into the starting corner, immediately pulling a gap with current championship leader, Jake Gange. An exciting battle for first continued throughout the whole race until the #85 rider from Princeton Kentucky made a calculated pass on the last lap. With only a few corners to the finish line, Lewis captured his second and consecutive win in the competitive Daytona Sportbike class for the MotoSport.Com Meen Yamaha team.
Going into race two, for the Sunday double header, Lewis was tied in points for the lead in the championship. Shortly after the start of the race, a red flag restart led Lewis to once again battle for the lead spot. Lewis ended up finishing fourth, placing him second in Daytona Sportbike points and in prime position to contest the championship at the last AMA Pro Road Racing weekend in New Jersey.
Lewis says, “This weekend provided great racing and I had a lot of fun doing two races in one day. I was able to make a last lap pass for the win in race one after a long battle. In race two I had a small issue but was able to manage a fourth and get some valuable points. Overall I’m happy to come out of Ohio with good results being not one of my favorite tracks. Now I will work hard over the break and come ready to fight for the Championship in New Jersey for my MotoSport.com/ Meen Yamaha team. ”
Rookie Daytona Sportbike rider Tucker Lancaster had his own list of challenges to overcome in Ohio. With limited seat time on a new track, he learned quickly and finished 17th in race one and 16th in race two. Lancaster goes into the last round second in the running for rookie of the year at a track he has a little more experience at.
Lancaster says, “Overall I feel like I had a good weekend at Mid-Ohio. Although we didn’t get the results, I felt like it was one of my best weekends of the year. With the limited track time it was tough to learn the track but I was fortunate to have Jason Pridmore there helping me out and I was up to speed by race time. I am training hard for New Jersey and hoping for a good end to the season.”
“It was a difficult weekend for all of us here at Mid-Ohio, fans and teams together. Sunday was jam packed with action and showed to have some of its own issues, but overall we are very happy with the results and are now going into the last round with Jake 7 points out of the championship. Tucker also rode well, considering he had to figure out the track and setup the bike with practically no track time,” says Meen Motorsports team owner, Ameen Sajjadi.
The Meen Team’s Superbike rider from Spain, Bernat Martinez, also had to learn the new track with limited seat time. Yet over coming these obstacles, while still getting accustomed to his new bike and team, Bernat rode his Proto-Tech /Blumac Yamaha R1 to a 13th place finish in race one and 11th in race two, improving his times drastically every time out on the track.
“Bernat has demonstrated he can learn new tracks fairly quickly, however this weekend we had unfortunately even less time to ride then most weekends. We are looking forward to the break and getting some much needed testing with the team,” comments Sajjadi.

Galfer USA Rider Jason DiSalvo Wins Daytona SportBike Race Two at Mid-Ohio
Oxnard, Calif. – July 23, 2014 – Rain at Mid-Ohio meant that all of the racing for round five of the AMA Pro Road Racing season was fit in on Sunday, July 20. Galfer USA came away from the day of double-header racing with a win thanks to Apex Racing’s Jason DiSalvo, who won the second Daytona SportBike race.

GEICO Motorcycle Honda’s Chris Ulrich held steady to earn two top-ten finishes. He was ninth and eighth on the No. 18 Honda CBR1000RR.

Jake Gagne led much of race one, but he was passed on the last lap, crossing the line an incredibly narrow 0.125 seconds behind the winner. Gagne finished second in race two, also, on board his Galfer-equipped No. 32 Red Bull/RoadRace Factory Yamaha YZF-R6. The double podium put Gagne into the Daytona Sportbike points lead.

A Weekend To Be Proud
Team Traction Control have come away from Brands Hatch with a growing sense of confidence for the future and pride in the young rider they have aboard the new Yamaha R6.
Going into round 5 of the British Super Sport Championship, TTC were feeling the pressure. The decision to change bikes midway through the season was not taken lightly but Team Principal Paul Bolwell and owner Keith Flint are determined for James Rispoli to have the opportunity to battle for top race results. The weight of that decision placed equal pressure on the young American to perform for his team as much as on Bolwell and Flint in making it. From free practice onwards that big decision to change bikes was already paying off, thanks to the skill of Rispoli.
“James went into free practice and immediately looked fast,” said an excited Bolwell. “The times don’t lie and he ended that first session with a top 5 place, right in touch with the leaders too.”
As team owner Keith Flint arrived from performing in Switzerland with his band the Prodigy – making the time to be with his team between huge European gigs – the expectation of a big performance was high. Sadly, disaster struck in the very early stages of qualification.
James began really well in the damp and tricky conditions and was sitting in 2nd place when he had a huge high-sider at Paddock Hill and badly damaged his ankle. Prior to that, his lap times had been right on pace. This piece of bad luck could have been the end of the weekend and a huge disappointment, however what followed was proof that Rispoli is deserving of Keith’s and Paul’s belief in him, and a demonstration of how committed this talented rider is to making an impression at BSB with Team Traction Control.
After a visit to the medical centre with his rock legend boss looking on, James started Saturday’s sprint race in 16th position on the grid, having missed most of qualification. The race started and immediately Rispoli was battling and in a race of just 12 laps he moved through the field to eventually finish 8th.
Flinty was loving it: “Mental weekend! Flying in to support the boys in-between touring made me even more pumped for it, so to see Rispoli tear through the pack and earn that 8th place was mega,” said Keith. “This bike is quick and we know he is, this change of bike was the right decision man.”
The crash meant Sunday was always going to be very difficult: the damage to James’ ankle was causing a lot of swelling and he struggled with changing direction on the bike. Even a blinding start couldn’t help: whilst riding hard in the front pack James ran wide, lost seconds that became incredibly hard to make-up and ended finishing in 12th place. Not the result that the potential has shown, but the manner in which it was done showed a determination and potential in this team that is very exciting.
“In terms of performance, times and results, this has been our best BSS race weekend to date,” Bolwell said, setting the scene for the rest of this season, “It was a shame about Sunday as we had a really good chance to improve on our previous days 8th place, but that’s racing eh! We now move on to Thruxton which is another of the circuits that James has yet to ride, after that we’re back to circuits we all know well and we will certainly be looking to be getting stuck in around those podiums positions.”
Last word to Keith, “Also wanna say thanks to Monster Energy for the great support this weekend and to the 100s of fans who rocked up for the signings – love ya!”

Progress Continues for Gessner at AFM
American Federation of Motorcyclists Round 4, Thunderhill Raceway Park, July 19-20, 2014
15 year old John “The Stalker” Gessner continued his streak of strong finishes with AFM last weekend, notching podium finishes in 4 expert classes as well as another top 10 finish in the club’s premier Formula Pacific class against 1000cc superbikes.
“John and I have worked together for 3 months now” said T&J Racing’s crew chief Mike Pascarella, “He’s young and hungry to improve. I’m really happy with the progress so far.”
Gessner did come together with another rider during the 600 Production race in Thunderhill’s notorious blind, off-camber Turn 3. “I made a small mistake making the pass,” explained Gessner, “I cut back into the apex of 3 before I’d really completed the pass, and I touched the other rider’s front wheel, which put us both on the ground. I’m sorry for the mistake, and I’m really glad nobody was hurt.”
After the team scrambled to get the bike repaired for the last race of the weekend, Gessner gridded up for the 750 Production race. Realizing that he would need to be on his game to fight with the other young guns at the front, he wasted no time getting back up to speed: “I knew what caused the crash, so I just didn’t think about it, plus I have a lot of confidence in the work Mike Pascarella and Dave Lanigan did putting the bike back together for me. I scrubbed the tires off during the warmup lap, then focused on getting a good start and leading the race. We did lead about half of the 750 Production race, but I missed a downshift on the last lap coming into Turn 14 and we ended up in second at the line by less than a bikelength. I’m really happy with the bike, and Mike Hammett from BP Racing lent us a motor for this weekend, I’m really grateful for that. The combination of Pirelli tires and GP Suspension has made the bike really easy to ride fast, and I’m able to focus on doing what Mike is telling me instead of chasing tire or setup issues.”
Official results, AFM Round 4:
750 Production: 2nd Place
750 Superbike: 2nd place
Formula 1: 2nd place
600 Superbike: 3rd place
Formula Pacific: 8th place
